The Schneider Electric LV426801 is an undervoltage release accessory designed for spring-actuated mechanisms within circuit breakers. This component operates on a dual voltage system, supporting both 24 V AC at 50/60 Hz and 24 V DC power supplies. It functions by de-energizing the spring mechanism, thereby preventing the closure of the associated circuit breaker when power is lost or falls below a critical threshold.

Applications & compatibility

This undervoltage release is commonly integrated into industrial control panels and power distribution systems where reliable circuit protection is paramount. It is particularly relevant for applications requiring automatic disconnection of power during voltage sags or outages, such as in motor control circuits, automated machinery, and critical infrastructure power management.
